Hi, I'm at the final stages of a short film that has 2 cows as the main characters.

I have a super strange bug that seems to only affect 1 of 6 Ornatrix hair objects. I have an octane tag on each of the objects set to transform/vertex. The scene crashes on one of the early frames each time. When I remove the octane tag from one of these 6 hair objects (one of the character's heads) the scene manages to render.

Please please can someone take a look at the scene for me? Ornatrix support won't look into this for me as they are blaming Octane for these issues as it's motion blur related.

I would be so grateful to have some help on this. It definitely seems like a bug as motion blur works great on some of the objects.

Thanks,

It may be failed due to low RAM/VRAM. Try with less hair counts and time-sampling values

Thanks for the fast reply Aoktar!

Yeah thought it could be this but we've also done tests with just the head object and it still fails.

Running 128gb and a 3090 here also.

Would it be ok to send you a simplified version of the scene to take a look at? Any thing else that I can try?

Sure, I'll be happy to test it.

I might be posting back again soon, but it seems to be working now.

It wasn't due to the number of hairs, but how many vertexs each hair had. Reducing this seems to be getting it past that frame now.

Good to hear! But checking the case may be helpful to fix the potential issue

Hi!

Yeah so it seems to be something to do with a memory build-up that doesn't clear or something. Reducing the vertexs in the hair got the render another 50 frames further before it stopped again. It doesn't crash, it just gets to a certain sample and stops.

Can I get your email to send you a wetransfer link with the scene?

Thanks
